Drive with caution — fix soon.
This code means the oil temperature sensor's voltage signal is higher than the normal operating range, which usually points to an open circuit, broken wiring, or a failed sensor. The typical fix is repairing the wiring or replacing the sensor. It's a common code and is usually fixable without major engine work.
$100 – $300
Varies by vehicle and root cause.
Usually yes, as the engine typically still runs normally. But the bad oil temperature reading can affect shifting and engine protection, so it's smart to get it checked before long.
Most repairs fall between $100 and $300. A wiring or connector repair is on the cheaper side, while replacing the oil temperature sensor with labor is toward the higher end.
It's moderate. The car usually still drives, but since the computer relies on accurate oil temperature for engine protection, you shouldn't ignore it long-term.
Usually not. A high signal most often comes from an open circuit or failed sensor rather than truly hot oil, but it's still wise to confirm the oil level and condition during diagnosis.
